What Is a Negative Interest Rate Environment?
Let me explain to you what a negative interest rate environment really means. It happens when the nominal overnight interest rate in a specific economic zone drops below zero percent. In this setup, banks and other financial institutions end up paying to store their excess reserves at the central bank, rather than earning positive interest on them.
A negative interest rate policy, or NIRP, is an unconventional tool where central banks set nominal target interest rates to a negative value, going below the usual zero percent lower bound.
Key Takeaways
- A negative interest rate environment exists when overnight lending rates fall below zero percent.
- In 2009 and 2010, Sweden and, in 2012, Denmark used negative interest rates to stem hot money flows into their economies.
- In 2014, the European Central Bank (ECB) instituted a negative interest rate that only applied to bank deposits intended to prevent the Eurozone from falling into a deflationary spiral.
- In a negative interest rate environment, financial institutions must pay interest to deposit funds and can actually receive interest on borrowed money.
Understanding a Negative Interest Rate Environment
The main reason for implementing negative interest rates is to boost economic growth. It pushes banks to lend or invest their excess reserves instead of facing a sure loss by holding them. The idea is that with rates below zero, banks, businesses, and households will spend money rather than save it, which stimulates the economy.
You should know that this environment encourages banks to issue more loans, households to purchase more goods, and businesses to invest extra cash instead of parking it in the bank. Because transferring and storing large amounts of physical cash is logistically tough and expensive, some banks are fine with paying negative interest on deposits. But if rates go too negative, they might exceed storage costs, changing that dynamic.
Overall, negative interest rate environments penalize banks for hoarding cash and aim to make borrowing cheaper for businesses and households, leading to more loans and more money circulating in the economy.
Risks of a Negative Interest Rate Environment
There are definite risks you need to consider in a negative interest rate environment. If banks start charging households for saving, it might not push consumers to spend more; instead, they could just hoard cash at home. This could even lead to a cash run, where people withdraw their money from banks to avoid negative interest fees.
To prevent such runs, banks might choose not to apply negative rates to small household deposits. Instead, they target large balances from pension funds, investment firms, and corporate clients. This way, those big savers are encouraged to invest in bonds or other options for better returns, while shielding the bank and the economy from the fallout of a cash run.
Examples of Negative Interest Rate Environments
Take the Swiss government in the early 1970s, for instance—they ran what was effectively a negative interest rate regime to counter currency appreciation caused by investors escaping inflation elsewhere.
More recently, the European Central Bank (ECB) pushed rates below zero in 2014. Then, in 2016, the Bank of Japan followed suit. Central banks in Sweden, Denmark, and Switzerland adopted negative rates between 2009 and 2012. These moves were to control hot money inflows and manage currency exchange rates as foreign capital poured in.
Special Considerations
Central banks in these countries have turned to negative interest rates to fend off deflation, which they worry could spiral out of control, devalue currencies, and undo economic gains since the Great Recession. So far, the negative rates are modest.
They've been cautious about dropping rates too far below zero because this practice is relatively new—the ECB was the first major institution to try it. Currently, the ECB charges banks 0.4 percent to hold cash overnight, the Bank of Japan charges 0.10 percent, and the Swiss central bank charges 0.75 percent.
